I am on first set. My lower aligner seems to have a space of 1/6th of inch between the teeth and the aligner on the inner sides, which causes obstruction to tongue while speaking. Aren't clear braces with computer aided fabrication supposed to fit snuggly against the teeth. The front inner fits snuggly. Is this symptom of some issue while taking molding.
Is there supposed to be space between aligner and teeth?

Space in Aligner
You are correct, clear braces are fabricated by taking initial impressions of your teeth which are then sent to a lab where they scan the impressions into a computer which then will fabricate your custom trays.
Acquiring Impressions with putty or PVS material ~ In the process of taking those initial impressions with a putty or PVS material, there are times that you may have a distorted impression. Usually this is caught by the lab technician and your dentist may call you back in to remake an impression. Distortion can happen by the technique that was used by the dentist or assistant, or during the shipping process.
Acquiring Impression with iTero (intraoral scanner) ~ In the process of taking your initial impressions with iTero, the dentist will use an intraoral scanner to acquire your impressions digitally. There is a lot of research produced that states the iTero is the best way to acquire impressions for accurate fit.
However; PVS material is used today and when taken properly can produce an equally great product.
Just another thought, as you are wearing your aligners, they should start out fitting tight and by days 5-7 you should fill a difference in how much easier it is to take them in or out. This is because the first days of each new aligner is moving the teeth and the last few days of the aligner are holding the teeth in the set position.
If you feel like you continue to have a space between your teeth and the aligner, have your dentist check the fit of the tray. It maybe something he is able to fix at the office or perhaps he may have to acquire new impressions to have your trays remade.
While you are at the dentist, ask them about whitening your smile using your Invisalign trays & a take home whitening gel. Our patients love this added bonus!
